I think the same as you. And I want to let her know exactly how I feel; she can normally sense it anyway. However, although my anger comes more often than I like, it is also fleeting (often lasting no more nthan minutes at a time). I know she is remorseful, the last time I mentioned the "emotions come in waves" she cried with apologies for a couple of hours (then depressed for another day). So what good does it do to bring it up?
My goal is to keep improving my marriage. If expressing my anger each time I feel it would help improve it, I would do it. But right now, I don't think it does. I can handle these emotions OK, they are not overwhelming and I am able to get myself into the present each time they occur. And like you, I believe these ripples will decrease in frequency with time. I guess only time will tell.
